壁面の反射に注目したセルオートマトン法による2次元騒音伝搬解析に関する基礎的研究

抄録

We focus on the reflection that causes on the surface of the wall, and research the two-dimensional noise propagation analysis by the cellular automata (CA) method. In our study, the CA method is confirmed that effective method about the fundamental phenomenon of the sound. However, a report of the numerical calculation by the CA method is none in the considering the sound reflection. So, we study the calculation accuracy of the reflection on the wall in using CA method. As a result, we confirm that the calculation of the CA method is comparable with the theoretical solution. Benchmark problem “AIJ-BPCA” is performed by CA method. As a result, we confirm that the calculation of the CA method is comparable with the calculation of the BEM and the theoretical solution.
